The MPS is a multifunctional autosampler and sample preparation robot for GC and GC/MS. The MPS provides modern analytical laboratories high throughput, high performance and unparalleled flexibility.
The following techniques are easily automated using the MPS:
Solid Phase Extraction SPE- Disposable Pipette Extraction DPX
- Dynamic HeadSpace DHS
- Headspace HS
- Solid Phase Micro Extraction SPME
- Thermal desorption of solids or liquids in µ-vial inserts (ATEX)
- Stir Bar Sorptive Extraction SBSE (GERSTEL Twister®)
- Automated GC inlet Liner EXchange (ALEX)
- Liquid sample preparation – Sample Prep by mouse-click
- Heated or cooled sample conditioning and agitation
- Parallel evaporation and concentration (mVAP)
- Reading and processing of barcodes
- Integrated weighing option

The MPS is easily and conveniently controlled from the GERSTEL MAESTRO Software – stand-alone or integrated with the Agilent Technologies ChemStation:
- Just One method and one sequence table controls the entire system
- Sample preparation is performed during GC analysis of the preceding sample ensuring highest possible throughput and system utilization
- Sample Prep by mouse-click
